You Did It!

Complete

Congratulations!

You did it! You got your board working and wrote your first CircuitPython code. There is a lot more to learn, but everything will build off of this tutorial, which covered basically all of the boring setup stuff. Future lessons will show you how to hook up sensors and buttons for input as well as use other outputs like screens and speakers.

The editor below still has the blinking LED code from the last step running on your board. Feel free to keep tweaking it before you move on, try changing the pin, the timing, or turning it into a different pattern entirely.

If you get stuck on anything down the line, the discord is always open.

# import lets us use code that other people already wrote for us
import board      # board knows the names of all the pins on your microcontroller
import digitalio  # digitalio lets us turn pins on and off
import time       # time lets us pause the program

# this variable represents the physical GP16 pin on the board
led = digitalio.DigitalInOut(board.GP16)
led.direction = digitalio.Direction.OUTPUT  # OUTPUT means we send power out, not read it

# "while True" means "repeat this forever"
while True:
    led.value = True    # turn the LED on
    time.sleep(0.5)      # wait half a second
    led.value = False   # turn the LED off
    time.sleep(0.5)      # wait half a second
